Google IAP Billing v4 offers a Multi-quantity purchase, how do we handle this?

The Google Billing v4 documentation mentions it being part of the product so I would assume Product.quantity

Everything is working otherwise.

Google Billing v4 is supported since Unity IAP 4.4.0, however Multi Quantity is not. See the official post:
Unity IAP package 4.12.2 is now available page-2#post-8319519
